Panic Stop, now no brakes and Puddle of fluid?

[chedeng]

andrewwynn, appreciate the detailed explanation and pictures. Excellent contributions to the forum. About my plans, i have decided to just splice instead of doing the whole line since time is a constraints. I need the car for work and can't afford to have the X5 down for a long time. Anyway, I bought the following and also the flare tools. Appreciate all the help you have been providing so far.

You need 3 copies of the 10mm union "intermediate piece". Definitely splice I'd have done the same knowing what I know now.

Do some sample bends to learn where the pipe doesn't bend. I'll try to take a picture how to line up the tool to make a perfect match. Since the radius will be different..

I can't tell if that has 3/16 size but some of the bends are tighter radius than possible with the tubing bender.

I just picked up some flare crow foot sockets ironically SAE since I need 11mm and 16mm and the metric size had neither.

I don't think I've ever seen the first bending tool at Harbor Freight before.
Definitely will keep my eye out when I'm there again.

Thank you andrewwynn very informative on getting the lines bent correctly.
100% agree with you on the Copper Nickel line, far superior to steel.

So some FYI: the factory fittings are all 7/16 nut. The normal 10mm nuts are 11mm nut. The 12mm normal nut is 12mm. The factory unions both 12 and 10mm are 5/8" which would be 16mm coincidentally.

I bought both SAE and Metric crowfoot sockets today

I used a set of spring bending cover to bend brake line tubing. I find it a lot easier to bend the tubing into the correct shape with just your hands. Also, you can bend the tubing into a tighter bend compare with most other tools out there.

Spring Bender will do the job. Won't be precise like this:

Finally got my brake lines in.
